"A new study published in in the journal Substance Use & Misuse found that people were more likely to correctly identify that a person in a photograph was a marijuana user than incorrectly guessing they did not use cannabis. Basically, if someone in a photograph is a stoner, people usually knew it."

“The present results provide evidence that individuals can discriminate between cannabis users and nonusers based on appearance alone,” the study said. “This ability is consistent regardless of the raters’ user status or gender, and age of the target.”
